2-乙基-2-恶唑啉的阳离子开环活性聚合和所得聚合物的纯化利用自动合成仪进行。平行合成了8种聚合物（500 mg标度）和40种聚合物（150 mg标度），考察了聚合的再现性和活性。采用H-1 NMR、MALDI-TOF质谱和在线凝胶渗透色谱等手段对所制得的聚（2-乙基-2-恶唑啉）进行了表征。
Living cationic ring-opening polymerizations of 2-ethyl-2-oxazoline and purification of the resulting polymers were performed utilizing an automated synthetizer. Eight polymers (500 mg scale) as well as 40 polymers (150 mg scale) were synthesized in parallel to investigate the reproducibility and the living character of the polymerizations. The poly(2-ethyl-2-oxazoline)s obtained such were characterized by means of H-1 NMR spectroscopy, MALDI-TOF mass spectrometry and online gel permeation chromatography.
